The Effect of Critical Thinking Skills and Mathematical Connection Skills on Students’ Ability To Solve Hots Problems
Full text linkThis study was conducted to explore the extent of the impact of students' critical thinking skills and mathematical connections in solving HOTS-type problems. Using a quantitative approach with a causal relationship model, this study took the subjects of grade VIII students at SMP Negeri 2 Sumber for the 2025/2026 school year period. From the total existing population, as many as 38 students were selected as a representative sample determined through the cluster random sampling method. All primary data were collected using a description test instrument that had passed validity and reliability tests to measure critical thinking competence, connection skills, and students' success in answering high-level questions. The data was then processed in depth through path analysis techniques with the help of SPSS 21 software.The main findings in this study reveal that critical thinking skills have a very strong direct influence on students' HOTS scores, which is evidenced by a beta value of 0.602 and a significance level of p < 0.001. However, quite contrasting results were found on the mathematical connection variable. This variable did not have a significant impact directly on students' ability to solve HOTS questions (beta = 0.115; p = 0.395). Furthermore, the results of the mediation test showed that no empirical evidence was found regarding the indirect influence of critical thinking on solving HOTS problems through the intermediary of mathematical connection ability. Simultaneously, the two independent variables tested in this model contributed 40.4% in explaining the variation in students' HOTS ability. This indicates that there are still around 59.6% of other factors outside of this study that also affect student achievement. In conclusion, these findings emphasize that the critical thinking factor is the most dominant and crucial element in supporting the success of junior high school students when facing complex mathematical problems.Pengaruh Kemampuan Berpikir Kritis dan Kemampuan Koneksi Matematis terhadap Kemampuan Siswa dalam Menyelesaikan Soal HOTSABSTRAKStudi ini dilakukan untuk mendalami sejauh mana dampak dari kecakapan berpikir kritis serta koneksi matematis siswa dalam menuntaskan soal-soal bertipe HOTS. Menggunakan pendekatan kuantitatif dengan model hubungan kausal, penelitian ini mengambil subjek siswa kelas VIII di SMP Negeri 2 Sumber untuk periode tahun ajaran 2025/2026. Dari total populasi yang ada, sebanyak 38 peserta didik terpilih sebagai sampel representatif yang ditentukan melalui metode cluster random sampling. Seluruh data primer dikumpulkan menggunakan instrumen tes uraian yang telah melewati uji validitas serta reliabilitas guna mengukur kompetensi berpikir kritis, kemampuan koneksi, dan keberhasilan siswa dalam menjawab soal-soal tingkat tinggi. Data tersebut kemudian diolah secara mendalam lewat teknik analisis jalur (path analysis) dengan bantuan perangkat lunak SPSS 21.Temuan utama dalam penelitian ini mengungkap bahwa kemampuan berpikir kritis memiliki pengaruh langsung yang sangat kuat terhadap perolehan skor HOTS siswa, yang dibuktikan dengan nilai beta sebesar 0,602 dan tingkat signifikansi p < 0,001. Namun, hasil yang cukup kontras ditemukan pada variabel koneksi matematis. Variabel tersebut justru tidak memberikan dampak signifikan secara langsung terhadap kemampuan siswa dalam menyelesaikan soal-soal HOTS (beta = 0,115; p = 0,395). Lebih lanjut, hasil uji mediasi menunjukkan bahwa tidak ditemukan bukti empiris mengenai adanya pengaruh tidak langsung antara berpikir kritis terhadap penyelesaian soal-soal HOTS melalui perantara kemampuan koneksi matematis.Secara simultan, kedua variabel independen yang diuji dalam model ini menyumbang andil sebesar 40,4% dalam menjelaskan variasi kemampuan HOTS peserta didik. Hal ini mengindikasikan bahwa masih terdapat sekitar 59,6% faktor lain di luar penelitian ini yang turut memengaruhi capaian siswa. Sebagai kesimpulan akhir, temuan ini mempertegas bahwa faktor berpikir kritis merupakan elemen yang paling dominan dan krusial dalam mendukung keberhasilan siswa tingkat menengah pertama saat menghadapi persoalan matematika yang kompleks.Kata Kunci:Kemampuan berpikir kritis matematis; kemampuan koneksi matematis; soal HOT
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
